I have a pool installed by Blue Haven pools. In the water line from the chlorinator to the pool, there is line that is basically spliced in to this water line and runs back up to the pressure release valve up on the filters. It broke off and I need to replace. I have tried Blue Haven but I can't figure out what this does. I would attach a picture but I can't figure out how to put in the message. It is like that drilled a hole in this water line and put this in almost as an after-thought.
